Association of lower urinary tract symptoms and OAB severity with quality of life and mental health in China, Taiwan and South Korea: results from a cross-sectional, population-based study
Abstract
BackgroundLower urinary tract symptoms (LUTS) and overactive bladder (OAB) symptoms have a substantial effect on quality of life (QoL). We report QoL and mental health results from a LUTS prevalence study in three Asian countries.MethodsA cross-sectional, population-representative, internet-based study among individuals aged ≥40 years in China, Taiwan and South Korea. Instruments included: Overactive Bladder Symptom Score (OABSS); International Prostate Symptom Score (IPSS); other International Continence Society (ICS) symptom questions; health-related QoL 12-item short-form (HRQoL-SF12v2); Work Limitations Questionnaire (WLQ); Hospital Anxiety and Depression Scale (HADS). Presence of LUTS was determined according to ICS criteria, with three symptom groups (storage, voiding and post-micturition). Post-stratification weighting matched the age and sex population distribution per country. Initial data analyses were based on descriptive statistics. Significance testing undertaken post hoc included: independent-samples t-test (differences in HRQoL between sexes and between individuals with/without LUTS; relationship between HRQoL score and OABSS; differences in HADS anxiety and depression scores between individuals with/without LUTS; association between HADS anxiety/depression scores and OABSS), chi-square test (association between LUTS prevalence and workplace productivity) and analysis of variance (differences in HRQoL score and in HADS anxiety/depression scores between…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 8,284 participants or records.
